Latest Patents

Esa Ottelin holds a patent for a "Method and apparatus for controlling distortion of fibre orientation in the head box of a paper machine." This innovative method involves an arrangement where by-pass flows of pulp suspension are directed through opposite passages lateral to the turbulence generator preceding the slice portion of the head box. The adjustment of the magnitude and mutual relationship of these by-pass flows is crucial for controlling the distortion of fiber orientation. The by-pass flows create a transverse flow in the discharge flow of the pulp suspension, compensating for any distortion in fiber orientation.
